Track recap
Compact review built from the authored track order and the same local-first concept progress already saved in this browser.
Start with complex numbers as points on one plane, then carry that same coordinate language into motion traced from x(t) and y(t).
Recap mode stays available, but it becomes useful after you save some local progress in the track.
How it works
Recap mode does not invent a second curriculum. It keeps the existing starter-track order, then changes the prompt and suggested action with the current mastery and progress signals.
Keep using concept pages
Recap links only jump you to the most useful surface for a fast review. The simulation-first concept pages still carry the real teaching work and keep the guided path intact.
Recap steps
Focus badges and button targets come from the current mastery and progress signals. The next ready checkpoint still stays in the loop.
Complex Numbers on the Plane is still the next guided step in this authored order. No finished quick test, solved challenge, or completion mark is saved yet.
Start here before moving into Parametric Curves / Motion from Equations.
This concept stays in the recap because it completes the authored track story, even if you have not reached it on this browser yet.
Capstone step after Complex Numbers on the Plane.
